Q. (a) Consider a diode circuit with RC load as shown in Figure. With the switch closed at t = 0 and with the initial condition at t = 0 that vC = 0, obtain the functional forms of i(t) and vC(t), and plot them.
(b) Then consider a diode circuit with an RL load with the initial condition at t = 0 that i = 0. With the switch closed at t = 0, obtain the functional forms of i(t) and vL(t).
(c) In part (b), if t >> L/R, describe what happens. If an attempt is thenmade to open switch S, comment on what is likely to happen.
(d) Next consider a diode circuit with an LC load with the initial condition at t = 0 that i = 0 and vC = 0. With the switch closed at t = 0, obtain the waveforms of i(t) and v (t).
Comparison of Analog-Modulation Systems The comparison of analog modulation systems (conventional AM, DSB SC, SSB SC, VSB, FM, and PM) can be based on three practical criteria:
